Help!
Which screw regulates the C#-D# trill on a Lorée English horn?
I am playing the 2nd movement of the Ravel piano concerto tomorrow in a concert and the C# won't come out when the left-hand D# is held down.

Press the LH Eb key and note which pad raises - that is the Eb/D# pad.
Press and hold the C# key, then press the LH D# key and watch the D# pad "wiggle" a little. That is why C# doesn't speak.
The adjustment screw is on the back of the D# pad rocker; close it slowly! keep feeling the C pad with ciggie paper and make sure it closes fully - if you over tighten that screw, C won't speak at all.
There are two little screws there - I am talking about the one actually on the D# rocker, not the one below it.

I tried tightening that one but it seemed to make things worse, rather than better, so I loosened it again. (I also find it impossible to hold all the necessary keys and check with the cigarette paper at the same time, so I was tightening, checking and playing).
What does the other screw do (the one just below)? Is there some sort of relationship between the two?
The horn is less than a year old and the bottom keys' action is not at all stable. My teacher has already regulated it several times for me since I bought it. I was intending to have him check it in my lesson this week but I have ended up not having a lesson because of a train strike.

The screw to the south of the Eb pad cup is to regulate the amount of free play to prevent the Eb pad being held open by the LH Eb/low B key.
The adjusting screw on the back of the Eb pad cup (at the highest point along its length) is the one that regulates the closure of the Eb pad cup with the low C key, so hold the Eb pad cup open (easiest way to do this is by holding the adjusting screw down on the end of the LH Eb/low B key) and check it by opening and closing the low C key. You can do this with your left hand and use the feeler gauge and screwdriver with your right hand.
Be careful you don't apply too much pressure when adjusting the screws as they have Teflon tips which can be crushed easily.

Thanks Chris.
I have just had another go, tightened the screw a huge amount (far more than I would have thought necessary). 1/4 turn made no difference, 1/2 a turn made the C# worse, 3/4 turn made it slightly better, so very cautiously I proceeded to tighten to about 1 1/4 full turns and it is now working.

Check the Teflon tip as it could be damaged if you've had to make that amount of adjustment.

How do I check the tip? And is it worth checking the tip before it is serviced in July? (I mean would I be able to do anything about it if it is damaged?)

If it is damaged, then there's nothingyou can do - your repairer will be able to replace it with a piece of nylon which is better than Teflon in this application.
